All Nordic Pure pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. Our non-woven, hypoallergenic and antimicrobial, synthetic MERV rated air filter media will not support growth of mold or bacteria, keeping your home healthier. As we say in the industry, "You have to move the air to clean the air". Our air filters use permanently electrostatically charged material that acts like a magnet to help dust cling to the air filter. This helps protect your unit, home, and family.

For people suffering with allergies and other breathing issues, choose our MERV 12 or higher MERV air filters to capture up to 98.9% + of allergens, pollens, pet dander and other airborne particles.

For MERV's 8, 10 and 12 we now offer *NEW IMPROVED* "Pleated MERV Plus Carbon"Odor Reduction Air Filters for eliminating odors in your home or office. Our electrostatic MERV media and new carbon media are pleated together to form an exceptional dust and odor control air filter. The new pleated design provides 3 times as much carbon media per air filter for better absorption.

The other MERV ratings available for this air filter have the MERV layer plus a flat poly Carbon layer. This option includes our electrostatic MERV media plus an added layer of polyester based media impregnated with activated carbon.

In both Plus Carbon options, the MERV media captures microscopic airborne dust, pollen, allergens, mold spores, pet dander, bacteria and particulates carrying bacteria, and viruses in the air for better indoor air quality. The high quality activated carbon media naturally deodorizes the air by absorbing and eliminating household odors that may come from pets, garbage, bathrooms, smoke, litter boxes, or cooking. It also removes levels of concentration of gases (VOC's) as well as particulates in the air while maintaining excellent air flow properties.

Nordic Pure air filters are made in the USA. Changing your A/C furnace air filter is the first step in ensuring your HVAC system runs at its optimal level this season. Generally, you should change your 1/2”, 1” and 2” air filters every 30, 60, or 90 days; the 4”, 5” and 6” air filters should be changed every 3 to 6 months, depending on your environment. Standard size air filters generally ship within 2-10 business days. Actual shipping time will depend on delivery address. We have been manufacturing air filters since 1960. Since HVAC units have advanced through the years, we have advanced our air filter media material too. Try them, and we are certain you'll be pleased.
